An Assessment of Heavy Metal Concentrations in Adirondack Waterfowl

Thu, 04/28/2016 - 22:53
Abstract: We analyzed heavy metal concentrations in waterfowl liver and breast tissue from ducks harvested within the Adirondack Park from October 3 to November 13, 2015. Interspecific, intersex, and feeding behavior variation in heavy metal concentrations were assessed. Waterfowl from two feeding behavior groups (diving and dabbling) were harvested from the watershed within a 50 mile radius of Paul Smith’s, New York. Harvested waterfowl species included mallard (Anas platyrhynchos), American black duck (Anas rubripes), common merganser (Mergus merganser), ring-necked duck (Aythya collaris), bufflehead (Bucephala albeola), and hooded merganser (Lophodytes cucullatus). Legal harvest of these species during regulated New York State duck hunting season allows for permissible use of internal organs for heavy metal determination. Dry weight (mg/kg) of digested liver and breast tissue samples were analyzed using atomic absorption spectroscopy. Due to unknown laboratory error, absolute concentration values were inaccurate, thus, rendering accurate analyses unfeasible. However, relative observable trends were able to be assessed given our data’s high precision. Analyte concentrations were significantly greater in liver tissues and there were significant differences between species. Variation in mercury, lead, bismuth, cadmium, chromium, and zinc concentrations in waterfowl serve as an indicator of the presence, cycling, bioaccumulation, and temporal trends of these metals in northeastern aquatic habitats.

Mycoremediation Potential of Pleurotus ostreatus in Logging Operations

Mon, 05/02/2016 - 10:43
Abstract: The unintentional spillage of diesel and hydraulic fluid is an unfortunate part of forestry operations and the traditional cleanup methods can be costly. Many studies have shown that white rot fungi (WRF) are capable of breaking down a wide variety of environmental pollutants, including diesel fuel. The purpose of this study is to evaluate the ability of a WRF, Pluerotus ostreatus, to breakdown hydraulic fluid. Soil and sawdust were mixed at a 1:1 ratio and jars had, 0%, 3%, 5% and 10% of their volume added in hydraulic fluid. All jars were fully colonized within two weeks and after 30 days the concentration of residual hydrocarbon was analyzed with an extraction. The results showed that the maximum degradation of hydraulic fluid occurred at 5%. In addition sawdust spawn was dehydrated at different temperatures, in order to assess possible field application. The only dehydration test that grew was the air dried sample.

Growth of Black Spruce and Tamarack in Response to Abiotic Variables

Tue, 05/03/2016 - 12:46
Abstract: The growth of black spruce (Picea mariana) and tamarack (Larix laricina) was examined in relation to the potential influences of pH, dissolved oxygen, conductivity, water temperature, proportion of canopy closure and depth to ground water in a northern Adirondack peatland ecosystem. 42 plots were constructed in a sphagnum dominated wetland and sampled for the above abiotic variables throughout the summer and fall of 2015. Heights, ages and periodic annual increment of 26 tamarack and 23 black spruce samples were determined in February and March of 2016. An age to height ratio and periodic annual increment for each species was then regressed against the above abiotic variable data in order to determine any influence of these data on growth rates of the conspecifics. Results show that depth to water table and increased exposure to light had a significantly positive relationship with the age to height ratio of tamarack. Periodic annual increment of tamarack had a significant positive relationship with decreasing light exposure. Black spruce’s age to height ratio had a significant positive relationship with dissolved oxygen (mg/L).

Paul Smith's Car Sharing Program: A feasibility study of implementing a car-sharing program at Paul Smiths

Mon, 04/22/2013 - 16:21
Abstract: Car-sharing is a program in which companies own a fleet of vehicles, insure them, maintain them, and offer memberships to people who wish to use them. Car-sharing is an eco-friendly way to use a vehicle when needed without the need to own one. These programs are environmentally friendly as well as cost effective. Paul Smith’s college is an environmentally friendly campus currently lacking an effective program to reduce emissions on campus. In addition to the absence of an efficient program to reduce emissions, Paul Smith’s College is experiencing a shortage of parking spots due to the excessive number of vehicles parked here. In effort to take further steps towards being an environmentally friendly campus and reduce the number of vehicles parked on campus, a feasibility study to implement a car-sharing program on Paul Smith’s College campus will be conducted.

Serving Those Who Served: A study of how small rural colleges can better meet the needs of their student veterans

Wed, 04/24/2013 - 23:14
Abstract: Currently many veterans are returning from combat and are seeking to obtain a post-secondary education at a college or university through the use of their GI Bill. However, it is unknown whether or not these institutions properly meet the needs of student veterans. The purpose of this exploratory study is to determine how and to what extent small rural colleges can better meet the needs of student veterans when compared to larger institutions that have more resources. Data will be collected through the use of primary and secondary research. The responses collected will then be aggregately analyzed to determine how the student veterans at Paul Smith’s College’s needs are being met and what they would like to see the college do to improve or implement resources and programs to better meet their needs. Additionally, the research plans to query veteran students at two larger universities in an urban setting. The results of this study will help small rural colleges become more military friendly, which could potentially attract more veterans interested in attending the college, and assist them with the transition from the military lifestyle to college and civilian life.

Alternative Management Methods for Acid Deposition in Lakes

Fri, 04/26/2013 - 18:09
Abstract: Acid deposition has been causing the acidification of lakes in the Northeast United States for decades. The result is lake ecosystems with abnormally low pH that stresses the organisms that live there. Management plans in place in the Adirondack Park have been working to remediate acidified lakes for the past few decades. Limestone (CaCO3) has been the generally accepted method for managing these lakes, in an attempt restore the lakes pre-impacted conditions. The purpose of this study was to evaluate the effectiveness of liming in reversing the effects of acidification, and to identify effective alternatives. Five alternatives were tested against limestone: Sodium carbonate (Na2CO3), Sodium bicarbonate (NaHCO3), Sodium acetate (CH3COONa), Magnesium carbonate (MgCO3), and Potassium carbonate (K2CO3). Double End-Point Titration tests were performed on all of the compounds, using both distilled water and lake water, to determine the relative alkalinity of each compound. Alkalinity is the measure of the ability of a solution to neutralize acid, also known as its "buffering capacity." Lake water was used in the titration tests in an attempt to mimic in-situ testing. The results of the titrations showed limestone proving to be the most effective in the lake water tests, with Magnesium carbonate and Potassium carbonate ranked closely behind. While limestone has proven to be an effective management method, its reliability is dependent upon the characteristics of the lake catchment, making it important to continue to look for alternative solutions.

Developing a Log Rule for Portable Sawmill Operators in Vermont

Fri, 04/26/2013 - 10:30
Abstract: Since the beginning of the 19th century, American lumbermen have been vexed by one of the unique questions of their trade; how do you estimate the yield of squared lumber to be cut from a round log? Since 1825, answers to this question have come in the form of log rules; a table or formula that estimates the yield of logs. These tables are in no way universal, and in some cases are crudely inaccurate. The shortcomings of these log rules have manifest differently in the various geographic locales and industry sectors where they are used. This study sought to identify such shortcomings as they pertain to a specific group of lumbermen; portable sawmill operators. These sawyers utilize modern bandsaw technology and have unique business practices, yet they estimate outputs based on century old log rules created for traditional sawmills. Through the use of semi-structured open ended interviews, technical and socioeconomic information was gathered from 7 sawyers in Vermont. Among other concerns, five of the sawyers expressed the need for a better way to estimate log yield. Based on their collective suggestions and technical approaches, a new log rule was created here to address sawyers’ needs.
